JIRA tracker@firebirdsql.org
Unavailable change domain type for existed field
-------------------------------------------------

                 Key: CORE-5539
                 URL: http://tracker.firebirdsql.org/browse/CORE-5539
             Project: Firebird Core
          Issue Type: Bug
    Affects Versions: 3.0.2
         Environment: firebird 64 bit windows sqldialect = 1
            Reporter: Konstantin Streletsky


my database has the following two domains:

CREATE DOMAIN DM_INTEGER AS
INTEGER;

CREATE DOMAIN DM_VC10 AS
VARCHAR(10) CHARACTER SET WIN1251
COLLATE WIN1251 ;

then I added a new table with column of type DM_INTEGER

CREATE TABLE NEW_TABLE (
    TEST_FIELD DM_INTEGER);

but when I tried to change the type of the column

ALTER TABLE NEW_TABLE ALTER COLUMN TEST_FIELD TYPE DM_VC10;

I got an error:

This operation is not defined for system tables.
unsuccessful metadata update.
ALTER TABLE NEW_TABLE failed.
New size specified for column TEST_FIELD must be at least 11 characters.
